Use a div and set the position of the div to absolute or fixed. The important thing is to set the z-index of the div to a large value such as: 10000

Position a well-styled button in the file box , the file box is fully transparent, so you only see the button but not the file box.
Clicking the button will click to the file box, and the button style is completely customized
